Answer:

A. LCM=72   B. GCF=7    C. 7(5+9)

Step-by-step explanation:

A. 8/2=4/2=2  9/3=3   Use the denominators to find the LCM. In this case, the LCM is 72.

B.  35/5=7   63/3=21/3=7    The GCF for these numbers is 7 because it is the only factor that they have in common.

C.   7 x 14=88     Since 5 and 9 don't have common factors, they work perfectly for this problem.

Determine the 28th term of the sequence -242, -251, -260
maxonik [38]
We can figure this out using the explicit formula.
f(n)=f(1)+d(n-1)
n represents the term we are looking for.f(1) represents the first term in the sequence, which in this case, is -242.d represents the common difference, which in this case, is -9.

f(n) = -242 + -9(n - 1)
f(n) = -242 - 9n + 9
f(n) = -233 - 9n

Now, we can input 28 for n and solve.

f(28) = -233 - 9(28)
f(28) = -233 - 252
f(28) = -485

The 28th term of the sequence is -485.
